McKnight stay behind while USC goes to bowl

Southern California tailback Joe McKnight did not travel with the Trojans to the Bay Area for Saturday's Emerald Bowl.

"He has some paperwork he needs to do and it's best for him to stay in LA so he can be available to finish it," Trojans coach Pete Carroll said.

Carroll did not have a timetable for McKnight's return.

"We don't know right now how long this will take," he said.

USC has previously said it was said it was investigating whether McKnight used an SUV registered to a Los Angeles businessman. The Trojans also declared three players academically ineligible on Monday.
